Product Description
Hydroxypropyl methylcellulose (HPMC) 2910 E5, also known as Hypromellose, is a semi-synthetic cellulose ether and viscoelastic polymer. It is derived from cellulose, a natural substance found in cotton and wood, and is widely used across various industries due to its unique properties.
Key Characteristics of HPMC 2910 E5:
- Solubility: HPMC 2910 E5 is soluble in a range of solvents, including water, organic solvents, and water-organic solvent mixtures.
- Thermal Stability: Unlike some polymers, HPMC does not gel when heated, maintaining its functional properties under a variety of temperature conditions.
- Non-Toxicity: HPMC is non-toxic to humans, making it a safe choice for applications involving direct human contact.
